Hi ,
I use Nastran in cad from 2019 version , From a reason I need to do a simulation with 2018 version.
There is no pin constraint only structural
How can create the pin constraint in the old version ?
thanks

Hello @eladm ,
You will need to create a Cilindrical Coordinate System and use that coordinate system with your structural constraint. See the video below:
Although the video was created with version 2021, the procedure for 2018 is the same. Most of the time I use workpoint to select the coordinates for the Origin, Axial direction (Z) and Radial direction (R).
You can also select sketch points, vertices or specify the coordinates yourself.
